VENTILATION.

Application filed main 13, 1925. Serial No. 15,383.

To all whom it may concern:

Be it known that'I, HENRY Ban'rz, a citizen of the United. States, residing at St. Louis, in the State of Missouri, have invented certainnew and useful Improvements in Ventilation, of which the following is a specification. c

My invention has relation to improve ments in heating and ventilating and consists of the novel features of construction and arrangement more fully set forth in the specification and pointed out in the claim.

The objectof the present invention is prnnarlly to heat and ventilate large bu1ld-- lng such as factories, wherein the gases,"

"'7 odors, turing carried on within quickly and continuously vented by the combined action of ventilating devices with the heating apparatus. Of course, in mild weather when the building does not require heating, the ventilating devices alone are necessary. 7 v

A further object of the invention is the effecting of a rapid and continuous exchange of the vitiated atmosphere for fresh, clean air without the production of well definedair currents, as these are harmful to the carrying on of certain operations, such as painting, where a smooth, even coat, unspoiled by dust, is required. vantages of the invention will be better apparent from a detailed description of the invention in connection with the accompanying drawings, in which- Figure 1 is a floor plan, more or less diagrammatic, showing the general arrangement of heaters and vintilators, in a building; Fig. 2 is .a vertical longitudinal section taken on the line 22 of Fig. 1 with parts broken away; Fig. 3 is a vertical cross-section through the building taken on the line 3-3 of Fig. 1; Fig. 4 is a sectional detail of the cowl of aventilator.

and fumes incident to the manufac- Referring to the drawings, B represents the building may be Further adheating devices 3, 8, 3"for the respective floors. y i

Each heater is provided-with a fan or blower b forforcing the heated air into the building. r i i The respective air-heating devices have hot air outlets l, i, 4 extending through the building wall and arranged to discharge heated air into the rooms above the respective floors. For drawing off the vitiated air from the respective floors, 1 provide a plurality of ventilating units V distributed over the entire floor area and uniformly spaced, these units being mounted, in the present case, on alternate pillars l, 1, 1 and extending up through the roof B. Each ventilating unit consists of three conduits 5, 5 and 5, con-,

conduit 5 terminatingjust above the 3rd floor F. The three conduits, however, are integrally formed (preferably) and open at their upper ends into a casing 6 having a revolving ventilator cowl 7 mounted on it. Thus the one casing 6 and cowl 7 serve the threeconduits 5, 5, 5 and the assembly of these parts constitutes but a single ventilating unit which serves all threefloors.

The distribution of the ventilators over the entire floor area inlsubstantially u-niformly spaced relation insures the rapid voiding of adorous gases, and prevents the formation of drafts or air currents by reducing to a minimum the distance the vitiated air :must travel before being voided. In other words the large floor area is subdivided into a large number of zones for the purpose of ventilation, such as those defined by the dotted circles lettered a in Figure 1, and the small amount of air to be exhausted from anyone zone requires so.

little draft through its particular ventilator that well defined air currents are not set Communicating with the inside of the building above each floor and the penthouse 2 is a damper 8, and in an outerwall of the penthouse, is a damper 9. hen it is desired to force fresh air into the building the damper 8 is closed and the damper 9 opened, and when it is desired to recirculate the air within the building the damper 8 is opened and the damper 9 closed.

Each conduit 5, 5 is provided with a gate 10 near ceiling of the room and said gate when opened is adapted to shut off that part oi the conduit below it. The function of this gate it) is to provide an alternate outlet for the noxious gases in the room when they are of such character that they adhere to the upper part of the room.

In the operation of the invention the heaters 3, 3, 3" are put into operation, and their fans 6 started so as to force fresh, heated air into the rooms. At the same time the fresh, warm air is entering, the vitiated air will be exhausting through the ventilator conduits as above described. Obviously, if desired, the heaters may be used merely as air supplying devices without first heating the air, or they may be dispensed with entirely when outdoor conditions are favorable to taking the fresh air into the building through the Windows.

Having described my invention I claim:

In a ventilating system, the combination with a room to be ventilated, of a pent-house adjoining said room, a valve-controlled opening between the pent-house and'said room and a valve controlled opening between the pent-house and the outdoors, an air-moving device within the pent-house and having an air outlet directed toward said room, and a plurality of ventilating units uniformly distributed over the tloor area of said room, each of said ventilating units comprising an air receiving conduit and an air-discharge cowl mounted at the top thereof, and said receiving conduit having two air intake openings in spaced relation and means for closing either of said intake openings.

In testimony whereof I hereunto afiix my signature.
